Experiences – good and bad - shape the growth and organization of the brain. These experiences ultimately impact emotional, social, cognitive, and physiological functioning across the lifespan. This workshop offers an exploration of integrating a nervous system lens into play therapy treatment. By understanding the relationship between the nervous system and behavior, this session delves into key concepts and practical strategies for therapists working with children and adolescents in play therapy. The training begins with an overview of the nervous system's role in regulating emotions, responses to stress, and overall well-being based on the work of Dr. Bruce Perry, Dr. Dan Siegel, and Polyvagal Theory. Participants will gain a deep understanding of the polyvagal theory and its implications for play therapy treatment planning and conceptualizing their clients. Therapists will learn how to assess nervous system states in their young clients and tailor play therapy techniques and interventions accordingly. They will leave with practical tools, increased confidence in working with nervous system dysregulation, and a deeper understanding of how play therapy can facilitate healing and growth in young clients.
